5V 8-Channel Relay Module na may Optocoupler Isolation (High/Low Level Trigger)
Ang 5V 8-channel relay module na ito ay may SMD optocoupler isolation para sa matatag na performance at maaasahang signal driving. Bawat channel ay sumusuporta sa napipiling high o low level triggering sa pamamagitan ng jumper settings, na nagbibigay ng flexible control options para sa iba't ibang control systems. Tinitiyak ng fault-tolerant design na hindi gagana ang relay kung maputol ang control signal line.
